The Outdoor multi-segment filter cartridge and the brand new pH+ Alkaline filter cartridge are your best allies to accompany you in your urban lifestyle. At school, at home, the office, the gym, yoga, or on the go, it's Alter Ego Frio.
The Outdoor and Globe-Trotter filter cartridges allow you to take your Alter Ego Frio bottle on hikes and expeditions into the wilderness, from the woods behind your house to the far reaches of the Amazon jungle.
This collection of products is named "Alter Ego" because, just like actor Matt Damon, we firmly believe that all humans are equal and that our Alter Egos - our sisters and brothers around the world - should all have unconditional access to clean water and sanitation.
Founded by Gary White and Hollywood star Matt Damon, Water.org is pioneering solutions to the global water crisis - breaking down barriers to give women hope, children health and families a bright future. This international nonprofit organization has already positively transformed millions of lives around the world through access to clean water and decent sanitation.
